what's the condenser for on a mechanical voltage regulator?

I have never tried it, actually, but concede that if it should start at all, it wouldnt run for long. Have you actually ever tried this? |

Have you actually ever tried this? I did. It won't run. Dan |

Used a plain piece of wire instead of points and condenser, touching the wire to ground manually and pulling it off to create the spark, seen by looking at a spark plug out in the open (grounded to the threads, of course). The spark generated in this manner was so puny it was hardly visible. When I added a condenser the spark was big and audible. |

Yes, the charging circuit will WORK without the cap, but the contacts on the relay will erode much faster than when the cap is present. Lots of RFI is a sign that the points are arcing, eliminating or reducing the arcing will make the contact points last longer. No "ifs, ands, or buts." |

perhaps you could help me, recently replaced generator and regulator in 56 Buick and ammeter shows no charge again. flashing for polarity doesn't help anymore. i have a battery disconnect on the ground terminal. with the old generator and regulator if i did the battery disconnect while the engine was running the engine would continue to run until the ignition switch was turned off; since change of generator and regulator when i open the battery disconnect the engine stops; just trying to understand whats going on. any comment? -- for full context, visit https://www.motorsforum.com/tech/wha...tor-52309-.htm |

thats wrong a alternator acts like a ac magneto in reverse form it can even act as as a bldc motor with a proper controler the gm 4pin ignition module system works on coliding magnetic fields bouth take place in the primery circuit a ac pulse is turned to dc pulse by the ignition module coming from a pick up coil the second pulse comes from the batery exactly from the potential diference from the alternator when those oposing waves hit ich other with high speed for exampel positive and negative pulses hit ich ither you get a spike down the high tension lead you can ither use ac with ac ore dc puls with ac it still will work those are called ac and dc magneto's so that alternator needs a condenser if not you get static in your baterry who will destroy it after some time doe the reson your alternatir is over charging the baterry with more volteg even tought that us not made you get more power considered the ignition system faster working electrical devices like electric motors etc thats the real reason that condenser is there for! those are low reving alternator build for working mashines like tractors if they are put in a car they will over charge a baterry you get a sport car out of your lazy normal ignition system this is considered as a waste spark ignition system as well by fiering on compresion and exaust at the same time your car will have more power
